What are the functional characteristics and usage scenarios of large-scale liquid nitrogen crushers?

The core function of the large liquid nitrogen crusher is to use the ultra-low temperature environment of liquid nitrogen (-196 ° C) to crispify materials and achieve ultra-fine pulverization by mechanical force, which is especially suitable for heat-sensitive, highly tough and viscous materials.I. Core functions1. Ultra-low temperature crushing: The material is rapidly cooled by liquid nitrogen, reducing its toughness, eliminating viscosity, and solving problems that are difficult to crush at normal temperature (e.g. rubber, plastic, oil and grease materials).2.Ultrafine granularity control: The particle size of the material after grinding is uniform, which can reach the micron level (usually 10-100μm), and some scenes can achieve the nanometer level to meet the needs of high-precision processing3. Low temperature protection of ingredients: Ultra-low temperature environment can prevent heat-sensitive ingredients in materials (such as effective ingredients in Chinese medicine, food nutrients) from being destroyed by high temperature, while preventing oxidized materials from deteriorating.II. Main characteristics· High crushing efficiency: Large equipment can handle hundreds of kilograms per hour, which is suitable for industrial continuous production.

· Extensive material adaptability: It can handle a variety of forms of materials such as solid, fiber, paste, etc., covering metal, non-metal, organic, inorganic, etc.

· Environmental cleanliness: The crushing process is carried out in a closed system, there is no dust leakage, and there is no liquid nitrogen residue, which meets the hygiene standards of the food, pharmaceutical and other industries.

· The particle size can be adjusted: by adjusting parameters such as pulverization speed, liquid nitrogen usage, screen specification, etc., the particle size of the finished product can be flexiblely controlled.

III. Typical application scenarios· Pharmaceutical industry: crush Chinese herbal drinks, Western medicine raw materials, biological products (such as enzymes, probiotics) to retain active ingredients.· Food industry: Process nut powder, fruit and vegetable powder, cocoa powder, and oily materials (such as sesame seeds and walnuts) to avoid nutrient loss and clumps· Chemical industry: crushed rubber, plastics, resins, pigments, etc. for recycling or the production of fine chemical products.· New materials industry: Process graphene, carbon fiber, metal powder, etc., prepare ultrafine powder materials, and improve material performance.· Minerals industry: Crushing non-metallic minerals such as ore, kaolin, talc and other minerals, producing ultrafine mineral powder with high purity.
